LR 510 atty on an eGo

[simprini]

On the various sites one can buy an eGo they have warnings against using LR attys with them which I don't understand. It would seem that LR and the eGo are a match made in heaven. Are these CYA warnings or am I really going to burn out the LR atty or eGo battery or both by doing this?

You can use a LR on a eGo! The battery will drain quicker than it does when using a standard atty. The LR atty's do have a shorter life expectancy since due to the lower resistance they run hotter. With a LR, user error is what usually kills them off quicker. They are best for dripping. 3 drops on a LR will get you about 6-7 nice draws vs 10 or so on a standard. Running them dry and overheating them will shorten their life. I have been using LR510's and LR306's on my 650 and 900mah eGo batts for about six weeks. No problems, but if you consider charge cycles on your batts you will be charging them more and reach their rated cycle count sooner with LR atty's than you would with satndard attys. For me the batts are a small price to pay for the increased vapor production of the LR's. Hope this helps

I've heard of maybe a handful of people that have had problems using lr attys on an ego.

Personally i have only used lr attys on my ego and have had it since june with no problems.

I was told not to use the LR's with the eGo PT's by the vendor I got it from, I guess they're ok with the regular non PT though.

I don't understand why LR atty's shouldn't be used with eGo PT's. It is supposed that when a device is connected to a USB the power is more consistent so it should work well. The only thing I can think of is that PT's provide higher voltage than batteries, what can be too much power for those atty's.

... and that is about it in a nutshell. The 650 and 900 mAh batts can handle 0.65A and 0.9A respectively whilst a standard 1.5Ohm atty draws 2.4A (@3.7V, 2A on the eGo), therefore stressing the battery = shorter life.

Building or using a simple box mod with "high drain" batteries the cost pales in comparison associated with proprietary battery replacement. For folks that have a device capable of handling an LR give it a whirl and see the difference... minimum batt for LR 14500 IMR. 500mAh capable of 4A

I'm planning to purchase a multimeter, do yo know how can we measure the electric charge (C) of our batteries using it?

 

[Bigham1]

Yes I do know how to measure the voltage!!

 

[pedromj]

I asked about the electric charge (Coulombs) not voltage

 

[Bigham1]

Calculating Coulumbs
1.1
Define the coulomb as the amount of electrical charge that 1 ampere transports in a second. This may be expressed as 1 C = 1 A x 1 s and makes the coulomb equal to approximately 6.24 x 10^18 electrons.

2.2
Examine an equivalent definition of the coulomb as the charge stored by a one farad capacitance with an electrical potential of one volt. This can be shown mathematically as 1C = 1F x 1V.

3.3
Use the definition of coulomb to calculate coulombs from current and time. We then have C = As where C is the charge in coulombs, A is the current in amperes and s is the time in seconds.

4.4
Express Coulomb's law. This is given as F = kq1q2/r^2 where F is the force exerted on charges q1 and q2, k is Coulomb's constant (8.987 x 10^9 newton square meters/coulombs squared) and r is the distance separating q1 and q2.

5.5
Solve for coulombs using Coulomb's law in Step 4 with q1 and q2 equal. We have F = kq1q2/r^2 => F/k = q^2/r^2 => q^2 = r^2 (F/k) => q = r (F/k)^(1/2).

This is a calculation, not a measure. Thus, I guess there is no way to get a direct measure from the battery, right?

 

[Bigham1]

None that I know of, Nor have found.

That makes sense. Good or bad I've actually been using LR on my stock 510 batteries as I wait for my Chuck. I wasn't planning on it but an LR got into the mix and after I'd used it going back to the stock 510 atty on the stock 510 battery was just lame. The Chuck'll be for home though and I wanted something more portable. I could pick up a small box mod for the purpose but I like the look and (imagined) feel of an eGo for when I'm out and about. As long as it's not going to melt down or explode in my hand I'll give it a shot and see how short the life is. I have a feeling I'm going to be using the Chuck 90% of the time so whatever my mobile solution is isn't going to get used -that- much. I think it's worth the life of an eGo batt to try it out
